Increased CO2 for Plants The benefits of increased carbon dioxide levels within a greenhouse are widely accepted and understood, and include earlier flowering, higher yields, improved stem strength, and larger flowers.

No set up or maintenance EZ CO2 is far less costly than tanks and generators and is incredibly simple to use. Just place it and leave it! It's that simple. You'll reap the benefits of increased CO2 PPM without any of the work or hassle of the other methods.

MEDIUM = MORE CO2 We've increased the amount of medium in our bags, compared to others on the market, so you get more CO2 for plants, and for your money.

Simple and uncomplicated EZ CO2 gives off no odors or heat, and is completely self-sustained. It's already giving off CO2 the moment you buy it, and it continues to produce CO2 for your plants for the next 6-8 months.

ABOUT EZ CO2 is a natural, safe, and inexpensive way of providing CO2 for your plants. CO2 tanks and generators can be expensive and time consuming, but EZ CO2 requires no set up or maintenance and is easy on your budget!

WHY ADD CO2? The benefits of increased CO2 levels within a greenhouse are widely accepted and understood, and often include earlier flowering, higher yields, improved stem strength, and larger flower size. This is because plants use the process of photosynthesis to convert water, sunlight, and CO2 into sugars and other materials essential to their growth and overall nutrition. When there is more CO2 in the air, plants become more efficient at absorbing it and processing it. Faster conversion of CO2 into sugars and nutrients results in faster plant growth. Additionally, plants take in CO2 through small pores on the underside of their leaves called stomata. When the levels of CO2 are higher, the plants do not need to open up these pores as often or as wide, resulting in less water loss and reduced likelihood of taking in damaging air pollutants.

HOW DOES EZ CO2 WORK? EZ CO2 houses a non-fruiting mycelial mass (fungus) and enough organic matter to sustain it for approximately 6-8 months. The fungus works opposite a normal plant: it breathes in oxygen and breathes out carbon dioxide (released 24 hours a day through the breather patch on the bag), essentially creating a natural, self-sustained, inexpensive CO2 generator. EZ CO2 is odor-free, produces no heat, and is already giving off CO2 as soon as you purchase it, there's nothing to turn on or set up. Simply place the bag of CO2 for your plants in your greenhouse and then leave it alone!

INSTRUCTIONS for CO2 for Your Plants After purchasing EZ CO2, place it in your growing area (1 EZ CO2 bag is recommended per 4' x 4' area) slightly above plant height. CO2 is heavier than oxygen, and will fall downward onto the plants. That's it! There's no need to refill anything or make any adjustments. DO NOT REMOVE THE BREATHER PATCH ON THE BAG OR OPEN/PUNCTURE THE BAG IN ANY WAY. After approximately 6-8 months the CO2 production will gradually decrease, and your EZ CO2 will need to be replaced. When you are ready to dispose of your EZ CO2, you may open the bag and dispose of the contents in your compost pile or mix it with soil, and the plastic bag can be recycled.

FAQS

Is it normal for the contents of the bag to change color or the bag to inflate? Yes. The bags will often start out brown and, over time, will turn a white-ish color. This is normal. It is the natural development of the mycelial mass. The EZ CO2 bag may also inflate, depending on the conditions it is in. This is also normal.

Do I need to open or remove the patch on the bag? NO. EZ CO2 is actively working the moment you purchase it. The bag should not be opened or the white Breather Patch on the front removed until disposal. Doing so will contaminate the mycelial mass and stop the production of CO2.

What is the white patch on the front of the bag? That is the Breather Patch. This perfectly sized patch allows oxygen to enter the bag and CO2 to exit while still protecting the mycelial mass from outside contaminants. Do not remove the Breather Patch.

Where should EZ CO2 go? 1 EZ CO2 bag is recommended per 4' x 4' area of grow space. Position the bag in your grow room over your plants, above plant height (CO2 will fall downward). Make sure that if you are hanging EZ CO2 over your plants you do not puncture the bag. It must remain sealed to protect the mycelial mass.

When should I use EZ CO2? EZ CO2 can and should be used throughout all stages of plant growth.

Q: Will the airflow from ventilation fans pulling air out and cooling the growlights diminish the co2 levels? If so, Should the outflow fan be turned off at all to increase CO2 levels to optimize the product?

Posted On: 1/10/2015By: Fritzy

A: Excellent question! That’s the tricky thing about CO2: it needs to be ventilated in a different way than oxygen in order for it to be utilized properly. Keep in mind that air- in general- is going to be pulled out when cooling your lights, so stale air, fresh air, and CO2 rich air will be lost to some degree when running your fans. But how you regulate your fans and airflow can make the difference between using a CO2 bag that helps your grow, and a EZ CO2
Homegrown CO2 bag that doesn’t do anything.
Now, the first thing to know is that CO2 is heavier than oxygen. Because it’s heavier than oxygen, carbon dioxide can be easily pulled away from your plants before it even gets a chance to hit them. When using CO2 it’s recommended to have the CO2 bag around the height- or a little below the height- of your grow lights so that a majority of it will fall on the plants. But how can you tell how much (if any) CO2 is in the room?
That’s where a Weather Station comes in handy. A good weather station will allow you to inspect and look at the CO2 levels in your grow room. This will be useful because from here, you’re going to need to do some experimenting with your fans. Gauge the amount of CO2 you have in the grow area with the ventilation schedule you have now. Then use the CO2 and see how much is in there: if there’s too much CO2, turn on a fan until the levels are low. If there’s not enough, adjust your fans so that the CO2 isn’t being pulled out so easily.
When it comes to doing this, it’s all about finding the sweet spot for your garden. While we can’t tell you how long to run your fans or at what percentage your grow needs to be at, too much CO2 will definitely harm your plants and raise the humidity and temperature in your grow to unsafe levels. That’s why you don’t want to simply stop the fans at a certain time, let the CO2 run, and then turn the fans back on. You might want to think about investing in a Speed Bully Fan Speed Controller, which will turn the fans down, allowing CO2 and air to slowly adjust to the perfect spot instead of too much or too little CO2.

Q: In the video it says to hang the bag over the plants. I have a small area that I'm growing and if I hang the bag over the plants it will be close to the vent for the heat. Will the Co2 the bag produces be wasted and sucked up through the ducting system?
Thanks,

A: Excellent question! What you should keep in mind when using EZ CO2 Homegrown CO2 bags is that CO2 is heavier than regular oxygen, so when the bags hang over your plants the CO2 will fall straight down on to them. When your plants receive the right percentage of CO2 their metabolism will speed up. On the other hand, if they don’t get the correct amount you will harm your plants or waste the CO2 all together.
Ventilation is key when using CO2, but as you’ve noted you’ll be sucking the CO2 out of the air before it can hit your plants if it’s right next to the vents. The area a CO2 bag will cover is a 4x4’, so if your grow are is that size or smaller, you might want to use a Speed Bully Fan Speed Controller in order to regulate how powerfully your vent fans will work.
No matter what you use, a small amount of CO2 will be lost because you’ll be venting- that’s normal. But if your fans are pushing air out/pulling air in full blast, the CO2 won’t have a chance to have any effect. If the CO2 doesn’t stay in there you won’t see any results from it, so to get around that you’ll want to regulate the speed of the fan. Doing that will help more CO2 stay in the grow area without the CO2 becoming too much for the plants.

Q: How many sq. ft. of grow space will each bag cover. We are setting up a large grow, 30 light's in an approximately 1200 sq. ft. facility. How many bag's would we need? Thx.

Posted On: 9/18/2014By: vincent pietro

A: Great question! Each EZ CO2 Homegrown CO2 bag will be able to cover a 4x4’ area, so given your grow area you’ll probably want to use 20-25 bags depending on the air ventilation and the space between your plants.
Keep in mind that CO2 is heavier than regular oxygen, so when the bags are above your plants the CO2 will fall down directly on to the plants. When your plants receive the proper amount of CO2 your plants’ metabolism will speed up, but if they don’t get the right amount you could harm your plants or just waste the CO2 in there.
Ventilation is key when using CO2. It’ll be a little tricky to regulate at first, but try to make sure that CO2 levels in your grow area are stable. If you don’t, you’ll be sucking the CO2 out of the air before it can hit your plants, essentially wasting the CO2. That’s why in the first time you use these bags you might want a few more than you really need. For your space, you really only need 20 or 21, but just to get in to the rhythm of using CO2 you might want 3-4 more, so about 22-25 total bags should be more than enough for that space without overloading your grow with CO2.

Q: Is this safe to use in a small closet grow w/ only fair ventilation??

Posted On: 12/2/2013By: donald

A: Yes, the EZ CO2 Homegrown CO2 bags, have a small venting patch on the front of the bag to allow a controlled amount to come out steadily over a 6-8 month period. It is best used directly hung over the plants.
